I was using MINT and suddenly keyboard stopped working properly, And if I want to type any thing then I have to hold on each key for 1-5 second. Now I have UBUNTU 14.04 (64-bit on HP-dv6) installed and I am still having the same problem. Please note that:

  1. Everything is updated.
  2. Keyboard is working while on Grub/BIOS perfectly.
  3. During Ubuntu installation when I tested the keyboard it was working too.
  4. Sticky keys, Slow keys, Bounce keys are all switched off.
  5. I’m using a fresh Ubuntu install and I don't have windows (dualboot).

Edit: repeat keys are off, if I enable it the keyboard goes crazy and keeps typing pressed letters

How should I proceed?

  • When you press NumLock, CapsLock and ScrollLock, do they lag?

  • Yes they lag too, I dont think its a lag because if i press the key normally then the letter wont be written event if I wait for it. I need to hold on the key to be written

    Check the settings/universal access/typing and ensure all are turned off. One of them adjusts the letter acceptance delay.

Reset to default

You seem to be having a problem with a keyboard that doesn't get reset properly during BIOS initialisation (after a BIOS upgrade?) or the keyboard is going bad.

Do the following:

  1. Edit /etc/default/grub and add atkbd.reset after quiet splash
  2. Save the file
  3. Run update-grub
  4. Reboot

The atkbd.reset kernel parameter will reset your hardware keyboard controller through software.

If you get syslog messages that contain keyboard reset failed, and you did not perform any BIOS upgrade, please remove the keyboard (if a laptop: download the service manual first), clean the connectors and the keys and re-insert it. If that doesn't help, replace it altogether as this is a sign of imminent hardware failure...
